Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or
Standard; Transfer of Listing.
On March 26, 2009, pursuant to the previously announced Agreement and Plan of Merger, Reorganization and Consolidation, dated as of December 19, 2008 (as amended, the "Merger Agreement"), among Noble Corporation, a Cayman Islands Company ("Noble-Cayman"), Noble Corporation, a Swiss corporation ("Noble-Switzerland"), and Noble Cayman Acquisition Ltd., a Cayman Islands company and a wholly-owned subsidiary of Noble-Switzerland ("Noble-Acquisition"), Noble-Cayman merged by way of schemes of arrangement under Cayman Islands law (the "Schemes of Arrangement") with Noble-Acquisition, with Noble-Cayman as the surviving company (the "Transaction"). Under the terms of the Schemes of Arrangement, each holder of Noble-Cayman ordinary shares outstanding immediately prior to the Transaction received, through an exchange agent, one Noble-Switzerland registered share in exchange for each outstanding Noble-Cayman ordinary share.
Prior to the Transaction, the Noble-Cayman ordinary shares were registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and listed on the New York Stock Exchange (the "NYSE")
under the symbol "NE." As a result of the Transaction, the outstanding Noble-Cayman ordinary shares were exchanged for Noble-Switzerland registered shares. Accordingly, Noble-Cayman requested that the NYSE file with the Securities and Exchange Commission (the "SEC") a Form 25 to remove the Noble-Cayman ordinary shares from listing on the NYSE.
Pursuant to Rule 12g-3(a) promulgated under the Exchange Act, the Noble-Switzerland registered shares are deemed registered under Section 12(b) of the Exchange Act. The Noble-Switzerland registered shares were approved for listing on the NYSE and began trading under the symbol "NE," the same symbol under which the Noble-Cayman ordinary shares previously traded, on March 27, 2009.
Item 3.03 Material Modification to Rights of Security Holders.
The information included under Item 3.01 of this Current Report is incorporated by reference herein.
Item 5.01 Changes in Control of Registrant.
In the Transaction, each Noble-Cayman ordinary share was canceled, and each holder of Noble-Cayman ordinary shares outstanding immediately prior to the Transaction received, through an exchange agent, one Noble-Switzerland registered share in exchange for each Noble-Cayman ordinary share. The description of the Transaction under Item 3.01 is incorporated by reference herein. As a result of the Transaction, Noble-Cayman became a wholly-owned subsidiary of Noble-Switzerland.
